Phase 2 Construction – Fairfax County Parkway WideningTo be determined as additional funding becomes available


Project Overview• Widening Fairfax County

Parkway to provide third lane in each direction

• Improvements to intersections within project limits

• Interchange at Popes Head Road• Includes access to future FCPA

Access to Patriot Park and the future extension of Shirley Gate Road

• Upgrades to shared use path • Stormwater management• NEPA document and noise study


Burke Centre Parkway Intersection Options

Prohibit Left Turns from Burke Centre Parkway• Improved safety and increased southbound and northbound

Fairfax County Parkway green time• Southbound traffic will only stop when pedestrian crossing

signal is activated


Burke Centre Parkway Intersection Options

Continuous Green-T (CGT)• Improved safety and increased southbound Fairfax County

Parkway green time • Southbound traffic will only stop when pedestrian crossing

signal is activated


Burke Centre Parkway Intersection OptionsNew Option Based on Feedback

Right-In / Right-Out• Eliminates existing traffic signal• Requires relocation of pedestrian crossing across Fairfax

County Parkway • Diverts southbound left turn traffic to Route 123 Interchange

Operational modifications to Fairfax County Parkway at Ox Road interchange are being coordinated with Fairfax County

Traffic analysis ongoingPotential improvements include:

• Exit/Entrance ramp improvements

• Transition from 3 to 2 lanes on Fairfax County Parkway


Route 123 (Old Ox) Interchange


Popes Head Rd/Shirley Gate RdExtension Interchange AlternativesCompressed Diamond

• Direct access to Shirley Gate Road Extension

• Access to Popes Head Road via new Connector Road

Double Roundabout• Direct access to Shirley Gate Road

Extension with connections to realigned Popes Head Road

• One bridge over Fairfax County Parkway

Split Diamond• Direct access to Popes Head Road

and Shirley Gate Road Extension• Similar to interchange at Fair Lakes

Pkwy and Monument Dr.


Typical SectionRaised Grass Median

Concrete Median Barrier


Pedestrian and Bicycle Facilities• The project corridor contains an existing 8-foot multi-use asphalt trail

from Lee Highway to Burke Centre Parkway:• Along east side of FCP from Lee Highway to Braddock Road• Along west side of FCP from Braddock Road to Burke Centre Parkway


NEPA Environmental Assessment Primary Points of Focus• Noise Study (23 CFR 772)• Air Quality• Section 7 of Endangered

Species Act• Section 106 of National

Historic Preservation Act• Section 404, 401 Clean Water

Act• Section 4(f) of Department of

Transportation Act


Noise Analysis Study Area

15

• As part of the environmental analysis conducted during the NEPA analysis, VDOT will conduct a noise impact assessment which will include:

Identifying noise receptors (such as residences, schools, parks, etc.)Conducting noise monitoring in the field Conducting noise modelingIdentifying impacts Designing and assessing mitigationPreparing and presenting noise study results and preliminary noise wall locations (if necessary) at public meetings.

66 dB Noise Abatement Criteria for Residential homes


Noise BarriersFeasibility

• Does it work acoustically?• VDOT requires that 50% or more of the impacted receptors

experience 5 dB(A) or more of noise reduction to be feasible;

• Can it be constructed?• Factors related to design and

construction include: safety, barrier height, topography, drainage, utilities, and maintenance of the abatement measure, maintenance access to adjacent properties, and general access to adjacent properties

AND

Example of location where sound barrier would not be feasible due

to spacing of driveways


Noise Barriers• Reasonable

• Cost-effectiveness• Maximum 1,600 sq ft of noise

barrier or less per benefited residence

• Design goal• 7 decibels of noise reduction at 1 impacted receptor

• Viewpoints of the benefited receptors• Democratic vote of the benefited receptors• 50% of the benefited respondents must favor construction• Partial mitigation may occur as a result of the vote
